What's the most likely cause?
Each case gives you a few observations about a system — a plant, a car, a computer, or a body. Read them, then pick the most likely cause from the six options.
Select a cause to highlight it, then hit Confirm diagnosis — no accidental taps.
Not sure yet? Run a test to reveal an extra observation for −30 pts. Some cases require at least one test before you can confirm.
A wrong guess costs 50 pts off the potential reward and shows you what would have happened if you'd followed that path — then you get to try again.
The runner-up cause earns half points — a thoughtful near-miss still counts.
Scoring: five cases, 200 pts each — full for the best answer, 100 for the runner-up, minus any test and wrong-guess penalties.
